Abstract: 960, 422. Panoramic kinematography. L. BRONESKY. July 25, 1960, No. 25874/60. Addition to 860,180. Heading G2E. Apparatus for projecting upon a screen, in proper side-by-side relationship, half-image portions of a composite picture arranged top-to-top or bottom-to-bottom in each frame of a motion picture film so that, as shown in Fig. 15, the width of each portion is longitudinal of the film, comprises a single projector and relay lens means for imaging the film frame on the inlet means of a pair of similar juxtaposed optical systems, disposed between the film and screen, the said inlet means being two anti-symmetric prisms (indicated by B1 and B2 in Fig. 14) corresponding, respectively, to the left and right image portion which they effectively rotate, in opposite directions by reflection at the prism faces,through 90 degrees into upside-down orientation, the two inverted images being in correct, or relatively reversed, left-right relationship, the said optical system further comprising each an erecting lens system and outlet deviating means (D1 and D2) for directing the two image-carrying beams to form a continuous picture on a screen. Each prism is mounted in a holder such as is shown in Fig. 5 for adjustable fixing, by means of screws and slots 57, 60, to a barrel containing to two optical systems. As shown in Fig. 12, the half-image portions on the film 101 are imaged at substantially unit magnification one on each of the prisms B1 and B2 by a lens system indicated schematically at 64 and shown in detail in Fig. 13. Light entering prism B2 (Fig. 8) at point a2 on inlet face 31 in the plane of the paper (from left to right in Figs. 9 and 12), passes into the prism and is reflected at 62 in silvered oblique face 30 (Fig. 10) to C2 in oblique face 37 and thence to d2 in oblique face 35 before leaving the prism at e2 of face 32 with lateral outward displacement, leftright inversion and 90 degrees total rotation. The lens systems U, V, W serve to erect the upside-down orientation of the image due to the prisms, and to form magnified real images on screen Y, and are independently adjustable for focussing by means of knobs 12 extending through slots in the barrel housing. The reversed left-right relationship of the two images is corrected by achromatic prism doublets D1 and D2 the deviation produced by these being controllable by means of knobs 12. The edge zones of the two image portions which will be projected in juxtaposition on the screen may be duplicated to allow slight overlapping, the increased intensity in this joining region being reduced by partial masking at the gate boundary adjacent the duplicated edges in the projection position. The image portions on the film may be laterally interchanged so that the left-right reversal of their images is obviated, and the beams emerging from D1 and D2 will not need to be crossed.

Title: Composition and method for making panel for printed circuits
IPC: C08F265/06
Filed: 1960-07-27
Abstract: A copper-clad plastic panel is made by applying to a copper panel a composition containing monomeric and polymeric methyl methacrylate bond, as an adhesion promoter, a polyhydric alcohol-polybasic acid condensation product in which at least 25% by weight of the acid component contains an olefinic bond in a position alpha to one of the carboxyl groups thereof, and then polymerizing the composition by heat and pressure.  Preferred adhesion promoters are obtained by condensing maleic, fumaric, itaconic or aconitic acid or anhydride with ethylene glycol, propylene glycol, glycerol or 1,1-isopropylidene bis-(p-phenyleneoxy) di-2-propanol.  The polymerizable composition p  may also contain additional monomers, cellulose esters, inorganic fillers and chlorinated hydrocarbon fire-retarding agents.ALSO:A composition which may be polymerized in contact with a copper sheet comprises a liquid mixture of monomeric and polymeric methyl methacrylate and, as an adhesion promoter, a polyhydric alcohol-polybasic acid condensation product in which at least 25% by weight of the acid component contains an olefinic bond in a position alpha to one of the carboxyl groups thereof, any other components being inert in respect of the adherent properties for copper sheet.  The mixture of monomeric and polymeric methyl methacrylate may be made either by dissolving the monomer in the polymer or else by partial polymerization of the monomer.  Other polymerizable materials may be present, e.g. methyl acrylate, acrylonitrile and polyethylene glycol dimethacrylate.  Adhesion promoters specified are condensation products of: (a) maleic anhydride and ethylene glycol; (b) maleic anhydride, succinic anhydride and ethylene glycol; (c) itaconic anhydride and ethylene glycol; (d) maleic acid and propylene glycol; (e) fumaric acid and 1,1-isopropylidene bis-(p-phenyleneoxy) di-2-propanol; (f) maleic anhydride and 1,5-pentanediol; (g) aconitic acid, o-phthalic anhydride and ethylene glycol; and (h) maleic anhydride and glycerol. The polymerization of the compositions may be promoted by the inclusion of catalysts such as benzoyl and lauroyl peroxides, tertiary butyl perbenzoate and azodiisobutyronitrile. Also present in the compositions may be additional substances such as cellulose acetate and butyrate, styrene-methyl methacrylate copolymers, calcium sulphate, carbonate and metasilicate, silica, clay, alumina, calcined aluminium silicate, antimony oxide and chlorinated biphenyl and terphenyl.

A synchronizing system comprises master and slave machines, the master machine driving a pulse generator A for controlling a synchronous motor C. The stator winding of the motor has its star-point connected to a D.C. source D, and the other stator-terminals are associated with electronic switches B1, B2, B3. The pulse generator may comprise three lamps each co-operating with a photo diode and a shield which is rotated by the master machine whereby the diodes are illuminated to provide pulses which are transmitted to the motor windings through the switches B1, B2, B3. In this manner; themotor performs six steps per cycle of operation of the pulse generator, but the frequency is so high that motion is uniform. An integrator E receives pulses from a second circuit of the generator A and delivers a frequency-proportional voltage through the switches B1, B2, B3, to the motor. Alternatively, the pulse generator may comprise mechanical contacts or hull effect devices.
